Simulation and optimization of separation sections in production process of propylene carbonate

Abstract

This paper mainly uses the Aspen Plus simulation software to simulate and optimize the distillation process of propylene carbonate collected and produced by CO2. We conducted the sensitivity analysis using Sensitivity module to obtain the optimization results of feeding position, reflux ratio and distillation ratio of the two columns. Product PC quality purity reached 99.6% and the product PG quality purity reached 99.9%. Both of the quality purities reached the separation requirements.
